Soil as a living system
Soil is not inert dirt. It is an underground city: bacteria, mycorrhizal fungi, earthworms, nematodes. When that community is thriving, plants grow proper roots and develop their own resistance.
Disturb it with compaction, synthetic fertilisers or repeated digging and the system falters. Plants weaken. Pests move in. Weeds fill the gaps.
Sawfly larvae on Solomon’s seal look alarming. In a healthy garden they are a season, not a crisis — birds find them, plants recover, and a spray would have taken the predators with the pest.
Building fertility the right way
Add organic matter. A 5–10cm mulch of compost or leaf mould in late winter feeds the soil life, suppresses annual weeds and improves structure in a single season.
Avoid routine digging. Worms mix better than any spade. Where ground is badly compacted, fork the worst of it, mulch immediately, and give it two or three seasons.
A dandelion at the edge of a path is early forage, a taproot opening compacted ground, and a reminder that “weed” is often just a plant in a place we had not planned.
The long view
Good soil is not a one-off fix. Each year it improves, the plants grow stronger, and the number of interventions drops. Feed the soil, and the plants take care of themselves.
